The start of spring break and a strong turnout for shows fronted by James Franco, Idina Menzel and Denzel Washington contributed to Broadway’s $2 million surge last week.

Overall, according to The Broadway League, the Street cumed $26,493,581 for 32 shows during the week ending March 23 — up from the previous week’s $24,465,468 and nearly $5 million more than the same frame a year ago ($21,709,082),

The Franco and Chris O’Dowd-fronted “Of Mice and Men” debuted with six previews last week at Longacre Theatre, playing at more than 95% capacity and grossing an impressive $688,832.

And in their third frames, Washington’s play “A Raisin in the Sun” and musical “If/Then” (starring Menzel) held up nicely, as did “Les Miserables” in week four.

“Raisin” brought in $1,107,163 for its eight performances, up from $981,488 the previous week. “If/Then” was also up and surpassed the $1 million mark ($1,008,303 vs. $929,267 the previous week). And enduring tourist fave “Les Mis” was nearly at the previous week’s level ($1,031,869 vs. $1,043,262 for the week of March 10-16).

“Rocky,” which opened to mixed, but generally favorable reviews, saw an encouraging week-over-week gain — rising to nearly $800,000 from about $640,000 the previous week.

“After Midnight,” which suffered two weeks ago after the exit of star k.d. lang ($381,020), surged last week (to $714,663) as new guests Toni Braxton and Babyface Edmonds stepped into the show.

Also on the rise by 5% or more were “Kinky Boots” (1,451,463), “Aladdin” ($937,099), “Bullets Over Broadway” ($782,289), “No Man’s Land/Waiting for Godot” ($647,289). “Mamma Mia” (573,443), “The Realistic Joneses” ($433,391) and “Mothers And Sons” (248,821).

The largest dropoff on the chart last week was “The Bridges of Madison County,” sliding by nearly 20% from the previous week to $385,394.

Joining “Of Mice and Men” as a newcomer last week were Tony Shalhoub vehicle “Act One” ($152,704 for four previews at nonprofit theater Vivian Beaumont) and “Cabaret” ($255,813 for three previews at Studio 54).
